摘要：

Two different polyimide semipermeable membranes have been prepared from two base polyimides of PMDA/ODA and BTDA/ODA by incorporation of lithium chloride with the respective poly(amic acids) and Subsequently leaching out the maximum possible lithium chloride by water Lit slightly elevated temperature. The water and various organic vapor permeability of the lithium chloride modified films has been found to be better compared to the respective control films. BTDA/ODA based polyimide films show overall lower permeability, (C) 2002 Elsevier Science Ltd, All rights reserved.
